Highlight Mesh Components 

Components of a mesh can be highlighted for visualization purposes.

In[1]:=

X mesh2d = DelaunayMesh[RandomReal[1, {20, 2}]]

Out[1]=

Highlight some edges and a face in the above mesh.

In[2]:=

X HighlightMesh[mesh2d, {{1, 1}, {1, 2}, {1, 3}, {2, 8}}]

Out[2]=

Highlight all the edges in a 3D mesh.

In[3]:=

X HighlightMesh[ConvexHullMesh[RandomReal[1, {30, 3}]], {1, All}]
